Leslie is moving toward the east-northeast near 38 mph (61 km/h). A motion toward the east-northeast with a gradual decrease in forward speed is expected through Sunday. On the forecast track, the center of Leslie will pass north of Madeira Island this morning, approach the southwestern portion of the Iberian Peninsula today, and move inland over portions of Portugal and Spain tonight and Sunday. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Leslie is expected to transition into a hurricane-force post-tropical cyclone later today or tonight. Weakening is forecast after Leslie moves inland over the Iberian Peninsula tonight, and the post-tropical cyclone is expected to dissipate by Sunday night or Monday. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). The estimated minimum central pressure is 980 mb (28.94 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected on Madeira Island this morning. Post-tropical Leslie will bring winds to near hurricane-force to portions of Portugal late today or tonight, and gale-force winds to portions of western Spain late today through early Sunday.

RAINFALL: Leslie is expected to produce total rainfall accumulations of 1 to 3 inches (25 to 75 mm) with localized amounts up to 5 inches (125 mm) across portions of Portugal and Spain this weekend.
